PUMP-OPERATING IEECHANISM.

original application filed December 11, 1922, Se ial No. 606,108. Divided and this application filed August To all whom z'tmay concern:

Be it known that I, JOSEPH H. OBERMAN, Jr, a citizen of the United otates, residing at Granville, in the county of Sioux and State of Iowa, have invented certain new and useful Improvements in Pump-0perating Mechanism, of which the following is a specification.

This application is a division of an application filed by me December ll, 1922, Serial The present invention seeksto provide novel means whereby a pump plunger may be easily reciprocated and will be held to arectilinear path, and also to provide a construction which will facilitate assembling and disassembling of the parts and firmly support the operating lever when the parts are assembled. These stated objects and 50 other incidental obj ects which will appear in the course of the following desciption are attained in such an apparatus as is illustrated in the accompanying drawing, and the invention resides in certain novel features which will be particularly pointed out in the appended claims.

In the drawing:

Figure 1 is a side elevation of so much of a pump as is needed to show my present 0 invention;

Fig. 2 is a rear elevation, and

Fig. is a vertical section.

The pump is supported by a well curb or platform (not shown) and includes a standard or sustaining tube 9.

in the upper end of the standard or sus 'taining tube. 9, l secure .a cap 29 which is provided on its upper side with flanges or lugs 30 to which the head or bracket 31 is secured. The said head or bracket consists of side members provided at their lower ends on their inner faces with recesses 32 corresponding in' dimensions and form to the lugs 30 so that, when the bracket or head is 4.5 in the position showr n Fig, 1 and the bolts 33 are in place, the bracket will be firmly supported in proper position to guise the plunger rod. Upon its outer side, one of the side members is provided with a ledge or shoulder 34 against which the heads 35 of the bolts 33 may bear so that the bolts will be prevented from turning while the nuts 36 are driven home, the necessity of employing an extra wrench or other tool to prevent turning of the bolt being thus over- Serial No. 659,961.

come. The side plates or members ofthis bracket or head are connected at their upper ends by a cap plate or bar '37 which is'secured. to and between the side plates by bolts 38 inserted therethrough, audit will, be readily noted uponreference to Fig. 1 that the upper extremities of the said side. plates are disposed out of vertical alinement with the sustaining rod 9 whereby the plunger rod may be slidablyc fittedthrough the said guide plate 37. At their lower ends, the side plates are further connected by a guide bar or plate 39 which is secured in place by bolts 40, and both guide plates 37 and 39 are provided centrally with angular openings ll through which the bar 42, which constitutes the upper extremity of the plunger, is slidably'fitted. One side plate is further provided with a ledge or shoulder i3 011 its outer side against which the heads of the bolts 40 may bear so that these bolts will be prevented from turning while the securing nuts are driven home, and a similar ledge or shoulder 44 is provided adjacent the upper end of the side plate to prevent turning of the bolts 38. A fu. .cru' .1 post 45 is mounted upon the cap 29 between the flanges or lugs 30 and projects upwardly and outwardly therefrom, as clearly shown in Fig. 1, the lower end of the post being pivotally held by the outer bolt A hand lever 46 is fulcrumed upon the upper end of this ,ost 45 and has its inner end pivotally attac ed to the bar 42 so that by oscillating the hand lever, the plunger will be reciprocated and the pump operated. The lower end of the bar 4-2 is secured within a yoke 47 which is firmly secured upon the upper end of the plunger rod48. The plunger rod extends down into the working cylinder and carries a plunger within the cylinder, as will be understood.

If repairs to the plunger or the cylinder should as necessary, the flat bar 42 which constitutes the upper extremity of the plunger rod is disconnected and removed from the guide bars or plates 39 and 37. The inner bolt 33 is then removed and the brackst or head 31 may then be swung rearwardly about the outer bolt 33 as a pivot. Ready access may then be had to the plunger and cyl nder to repair or renewthe parts.

Having thus described the invention, what is claimed as new is:

1. In a pump, the combination of a sustaming member, a head consisting of side plates disposed at the upper end of the sustaining member guides disposed between the side plates at one side of the vertical plane of the sustaining member, securing bolts inserted through the side plates and the guides and through the side plates and the upjoer' end of the sustaining member respectively, av plunger rod disposed at the side of the sustaining member and playii'ig; in the guides and means mounted on the sng member to operate the plunger red. 7. 2,111 a pump, the combination of a sustaining member, a plunger rod, flanges on the upper end of the sustaining meinben a heed comprising side plates disposed against said fif'iiiggesi bolts fitted through said flanges and the side plates one of said bolts being removable to permit pivotal ad ust- Lessee? ment of the side plates upon the remaining boiti. des carried by said side plates and re erving the upper extremity of the pine {301' rod, and an operatin member mounted upon the sustaining member and eonneeted with the said plunger rod.
